Battery Life

The LG G4 comes with a removable lithium-ion battery rated at 11.55 Wh (3,000 mAh at 3.85V), which is slightly larger than the 11.2 Wh battery included with the LG G3 due to a slight voltage output rise. Due to improved power consumption on the SoC and display fronts, the LG G4 should have better battery life than the pretty disappointing figures the LG G3 produced for a first-generation 1440p smartphone.

During my time with the LG G4, I found the battery life to be pretty decent for a phone with a powerful SoC and high resolution display. Let’s take a look at what the benchmarks say.

The battery life results for the G4 back up my real world experiences using the device over the course of a few weeks. The handset features battery life similar to the Galaxy S6 in all situations but LTE web browsing, where the G4 outperforms the S6 by 16%. Compared to the G3, which had pretty mediocre battery life for a flagship, the G4 delivers 29% better battery life with similar hardware: an impressive achievement.
